COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 568,381, dated September 29, 1896.

Application filed May 2'7, 1896. Serial No. 593,340. (No moclelJ T0 at whom it may concern.-

Be it known that 1, CHARLES E. THOMPSON, a citizen of the United States, residing at Leesburg, in the county of Loudoun and State of Virginia, have invented certain new and usef 111 Improvements in Combination-Tools and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to combinationtools; and the object is to provide a tool, such as a bit-brace, with a variety of elements, whereby the same can be converted into several other forms of tools, such as a wrench, screw-driver, ratchet-drive, and the like; and to this end the novelty consists in the construction, combination, and arrangement of the same, as will be hereinafterv more fully described, and particularly pointed out in the claims.

In the accompanying drawings the same figures of reference indicate the same parts of the invention.

Figure 1 is a plan View of a ratchet-bit brace embodying my invention. Fig. 2 is a similar view, partly in section, of the tool arranged as a simple bit-brace. Fig. 3 is a similar view of the tool arranged as a simple lever, monkey, or pipe wrench. Fig. 4 is a similar view showing a circular monkey or pipe wrench; Fig. 5, a view showing the same arrangement as a circular-ratchet drill for working in corners or other confined places; Fig. 6, as a straight-ratchet screw-driver; Fig. 7, as a lever-ratchet screw-driver; and Fig. 8 is an elevation of the device employed as a stationary machine drill for general blacksmith and machine use.

1 is the ordinary brace-arm formed with a polygonal end 2, and its head 3 is provided with a countersunk orifice 4, and 5 is the detachable handle, mounted on a sleeve 6, the ends of which are formed with tapered poly onal recesses 7 and 8, one of which conforms to and is adapted to receive and retain therein by friction the polygonal end 2 of the bracearm 1, and the other, in a similar manner, either of the polygonal studs 9 or 10 of the wrench 12. When so engaging the stud 9 and brace-arm 1, the tool assumes all the functions of an ordinary carpenters brace, as shown in Fig. 2.

The wrench 12 comprises the rigid jaw 13 and the sliding jaw 14, traveling on an elongated thumb-screw 15. The contiguous parallel faces of the jaws 13 and 14 are serrated, as shown, to enable them to grasp a cylindrical body, such as a bolt, pipe, or the like, and of course the parallel faces of the jaws, any regular or irregular polygonal sides, nut, or other article. The tapered angular recesses 1G in the faces of said jaws adapt the wrench to the tapered square heads of all sizes of ordinary boring-bits, drills, screwdrivers, and the like, as well as cylindrical bodies, such as the cylindrical shanks of twistdrills, pipe-fittings, &c.

As shown in Fig. 5, the ratchet-cylinder 17 is secured by its tapered polygonal shank 18 between the jaws of the brace, and in this form can be used as aleft or a right hand drill by simply oscillating the handle 5. As shown in Fig. 6, thehandle 5 is connected direct to the shank 18 of the ratchet-cylinder, the spring-stud 19 on the handle engaging the orifice 20 in the sleeve 6. This connects the handle 5 and the sleeve 6 rigidly and forms a perfect right or left hand ratchet screw-driver, and by applying the brace-arm 1 to the handle 5 a lever-ratchet screw-driver is formed.

In Fig. 8 I have shown the device fitted to an ordinary frame 21, provided with an adjustable feed-screw 22, the taper end 23 of which forms the center for the countersunk orifice 4. In this form a perfect blacksmiths ratchet-drill is produced for drilling work too heavy for the ordinary brace.

The ratchet-cylinder 17 is provided with the milled ring 24, the recesses on the inside of which engage the arms of the pawls to throw them into or out of contact with the series of circular teeth in the body of the cylinder, and said ring 24 may be manipulated to form a right-hand ratchet, a left-hand ratchet, or, by having both pawls engage the teeth at the same time, the shank'18 and the cylinder 17 are locked and act as onepiece.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of my invention Without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is

1. A sectional brace comprising the ratchetcylinder, the Wrench, the handle, and the brace-arm, arranged to cooperate substantially as and for the purpose set forth.

2. A sectional brace comprising the ratchetcylinder, the Wrench, and the handle mounted upon the sleeve formed with the polygonal recessed ends, substantially as and for the purpose set forth.

3. A combination-tool of the class described, comprising the ratchet-cylinder 17, having the polygonal shank 18, the wrench 12 formed with the polygonal studs 9 and 10, the handle 5 mounted on the sleeve 6 having the tapered polygonal recesses 7 and 8 in the brace-arm 1, having the polygonal end 2, substantially as and for the purpose set forth.

4. A tool of the class described, comprising the ratchet-cylinder 17, having the polygonal shank 18, in combination with the handle 5 provided With the spring-stud 19, and mounted on the sleeve 6 having a tapered polygonal recess 9 and the orifice 20, substantially as and for the purpose set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

CHARLES E. THOMPSON.
